SPECIFICATION forming part. of Letters Patent No. 418,727, dated January 7, 1890. Application filed T111y15, 1889. Serial No. 317,635. (No model.) I

To all whom it may concern:

Be it known that I, WILLIAM S. KISINGER, a citizen of the United States, residing at Dayton, Campbell county, Kentucky, have in 5 Vented new and useful Improvements in Oar-i Wheels, 850., of which the following is a specification.

My invention relates to car-wheels, gearwheels, pulleys, &c., involving rims or surfaces subject to Wear, and which it would be desirable to replace when worn without the cost and labor of replacing or renewing the entire wheel; and it consists in a construc- "tion of such wheels whereby a cheap and'ef-' I 5 fective wheel made up of interlocking parts is produced, the Wearing-rim of which can be renewed from time to time without detach-- ingthe hub portion of the axle.

The invention is illustrated in the accom- 2o panying drawings, in which- Figure 1 is a perspective View of the hubportion detached; Fig. 2, a similarview of the rim portion detached; Fig. 3, an axial section of the complete wheel, taken through the holding-lugs, showing the relation of the two parts in position; Fig. at, a chord section of a portion of the rim through the spoke.

and holding-lugs, showing the relation of the spoke, lugs, and retaining-wedge; Fig. 5, a side elevation of the wheel complete, showing a modification of the holding device; Fig. '6, a side. elevation of the wheel complete, showing a disk-centerin lieu of the separate spokes; and Fig. 7, a section through part of the disk 3 5 and rim, showing the relation of parts.

Referring now to the drawings, the Wheel A is composed of two partsto wit, a central hub portion or spider A and a separate detachable rim or annulus A The spokes s 40 are cast with terminal arcs, forming equal parts of an entire circle corresponding with and fitting the inner surface of the outer rim or annulus A and these two contact-surfaces may be slightly coned to insure a driving fit,

5 though this is not regarded as essential. At the front and rear of each spoke are cast projecting brackets ct, having their outer radial faces correspondingly eccentric. Above the brackets a the front edge of the spoke is The rim or annulus A is cast with aproper exterior contour for the ultimate use of the wheel-that is to say, it is grooved,cogged, or flanged to form I a belt-pulley, a cog-wheel, car-wheel, &c., as required. In the present illustration it is pro- 5 5 vided with a bearing-tread and flange 0 to serve as a car-wheel upon a guiding-track. The inner surface of the annulus A is provided with a series of concentric lugs b, slightly eccentric upon their faces, as indi- 6o 'cated in Fig. 2, and inclined spirally upon,

one adjacent side, as indicated in Fig. 4. A corresponding series of eccentric lugs e is arranged in. a line parallel with the series of lugs 19, having the function of abutments for the rear edges of the spokes when in position as 'a holding-abutment against lateral strains.

In placing the two parts A A together the hub portion A is inserted sidewise in the annulus, the ends of the spokes passing between each two adjacent pairs of lugsb c, and then, by rotating the hub portion in the proper direction in relation to the rim, the

inclined eccentric faces of the lugs b e bear against the corresponding eccentric faces of the brackets a, thus centering the hub portion in the annulus and securing the same radially. Atthe same time the spirally-inclined inner sides of thelugs b bear against the spirally-inclined front edges a? of the spokes and force the spokes back against the rear abutment-lugs e, thus securing the spokes edgewise between the two sets of lugs and bringing the rim to a true gage in relation to the spokes and hub. The parts being driven home to a firm contact upon the described seats, it will be seen, Fig. 3, that any side strains upon the flange csuch as are experienced in side lurching of cars or in passing curves-are taken by the abutment 9o lugs e in contact with the spoke system, while strains in the opposite direction are taken by the sides of the lugs bin contact with the front edges of the spokes. The weight of the car upon the axle is taken by 5 the radial contact of the spokes against the inner surfaces of the annular rimA and upon the contact-faces of the brackets a and lugs 17, &c.

Any suitable means for securing the two parts A A together may be employed; but as a simple, eifcctive, and economical construction for this purpose we form in the castings one or more shallow grooves or re cessesg across the outer facesof the spokes 3, parallel to the axis, in proper relation to a pair of the lugs b a when the parts are in position, Figs. 4 and 7. \Vhen the spokes are driven home, a wedge or key .2 is driven into the groove or recess g, which. bears against and behind the adjacent lugs b e, which effectually prevents the slipping back of the parts, and the wedge or wedges may be held by a pin, if required. In lieu of wedges pin g, Fig. 5, may be driven into a groove formed by corresponding half-grooves formed, as described, upon the corresponding inner face of the annulus A} and theou ter periphery of the spokes and registering when the parts are driven home. A v

, Instead of spokes, the central or hub portion of the. wheel may be formed as a disk with Suitable openings, the construction and fittingtog ether being otherwise the same.

I claim as myinvention and desire to secure by Letters Patent of theUnited States 1 The combination, in a two-part wheel or 'p u lley,of a rim having two parallel series of lugs upon its inner side with concentric faces, and a hub portion having spokes or projections adapted to pass laterally between consecutive lugs of the rim and by partial rotation of the parts engage betweenadjacent opposite lugs, said spokes being providedat one or both sides with brackets or lugs having eccentric surfaces adapted to engage radially by frictional contact with the eccentrio or inclined surfaces of the rim-lugs, substantially as set forth.

2. A wheels1 1ch as a pulley, cog-wheel, car-wheel, &c.com posed of two interlocking seetio ns to wit, a centrahspider or hub section and an outer rim or annulus-said, sections constructed as follows: (a) the rim having on its inner surface two parallel series of circumferential lugs having eccentric faces andsone series having spirally-inclined inner sides, and (b) the central or hub section having at both sides a series of radial brackets with eccentric arc-faces to match and engage with the lugs of the rim and with spirally-inclined front surfaces at one side above the brackets to engage the sides of one series of lugs uponthe rim and force the hub portion against the rear system of lugs and hold it laterally between the two systems of lugs against lateral displacement, substantially as set forth. I

3. The combinatiomin atwo-part wheel or pulley, of a rim haying two parallel series oflugs upon its inner side and one oranore bfiQking-lugs', anda hub portioii having spokes adapted to pass laterally between consecutive logs. of the rim and by partial rotation engage between and uponadjacent opposite lugs by means of bracket projections and be held by frictional contact of eccentric surf aces, and a wedge adapted to pass and engage bet-ween a spoke and backing-lug, sub stantially as set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses. V
